Thin supported furniture-part specification

Hardboard backs and drawer bottoms, prepared for a close fit.

Give cabinet backs and drawer bottoms their own part specification. We supply thin hardboard and cut parts with the actual face construction, finished size and orientation agreed for your furniture. Send the groove or rebate details and assembly drawing; a representative fit check connects the board thickness to the supported cabinet or drawer you are making.

Hardboard cabinet back and drawer-bottom components fitted into furniture assemblies

Choosing your material

How should hardboard furniture backs and drawer bottoms be specified?

Begin with the supported furniture part and its assembly interface, then select the hardboard thickness, face and processing method.

A cabinet back can slide into a groove, sit in a rebate or fix onto a supported frame; a drawer bottom is captured by a different groove and hardware assembly. The drawing must state finished size, face orientation, fit allowance, support, fixing and quantity for each part.

01

Cabinet and wardrobe backs

Coordinate the complete carcass, groove or applied-fixing method, perimeter and intermediate support, service openings and visible interior face.

02

Drawer bottoms and infill parts

Define the groove, capture depth, finished size, drawer or frame dimensions, intended support, visible side and assembly sequence.

03

First fit and flat packing

Fit a production-representative cut part, verify squareness and orientation, then protect thin labelled parts on continuous flat support.

CUZI MDF hardboard is offered in 1.5–5 mm thickness at 810–960 kg/m³. Choose the actual product within that range and pair it with the part support, drawer or cabinet construction and acceptance method in your furniture design.

Give machining operations their own face and datum, and carry the same physical feature through both views.

Trial the panel and the actual receiving furniture together. Groove width is compared with completed thickness, groove-root distance with cut size, and support span with the intended drawer or cabinet use. A finish or coating is included in the selected completed thickness; the actual sample establishes any extra build and the resulting fit.

Buyer questions

Common hardboard furniture-back and drawer-bottom questions.

Use these answers to connect the selected sheet, fitted component and repeat furniture order.

Is hardboard suitable for cabinet and wardrobe backs?

Yes, for supported cabinet and wardrobe backs with the groove or applied fixing, perimeter support, panel size and assembly method defined. Specify the actual smooth and reverse faces, finished dimensions and thickness tolerance. The complete cabinet design determines the required support and bracing performance.

Can hardboard be used for drawer bottoms?

It can be considered for drawer bottoms supported by the released drawer construction. The designer should define drawer size, contents, groove capture, front and back joints, support and hardware. A representative drawer should be assembled before repeat production.

Which side of hardboard should face inside the cabinet or drawer?

The order must identify the visible face. Some hardboard has a smooth face and a screen-pattern reverse; other constructions may differ. Record face and reverse in drawings, labels and packing instructions so installers receive clear orientation.

How should the groove fit be specified?

Define the actual groove width, depth and position, hardboard thickness and tolerance, any coating or laminate build, finished panel size, insertion allowance and assembly sequence. Approve the fit using production-representative materials.

How should thin hardboard parts be packed?

Support parts continuously on a flat base, use clean separators and top protection, protect corners and edges, control strap positions and pressure, keep packs dry and label each furniture or part group while keeping the thin sheets flat and supported.

What should a hardboard furniture-part RFQ include?

Send cabinet, drawer or frame drawings; part IDs and quantities; finished dimensions; thickness and tolerance; face/reverse and finish; groove, rebate or fixing details; holes and cut-outs; first-fit plan; labels, packing, destination and timing.

Can I request samples for this application?

Yes. Our product samples are free and usually available from stock. Tell us which board and finish you want to compare, including the actual face and reverse, thickness and fit in your groove. You pay the courier charge, which can be credited against the formal order amount. We confirm sample availability, preparation and estimated transit time before dispatch.

How do I calculate a drawer-bottom cut size from its grooves?

Start from the actual clear distance between the drawer's inner faces, add the groove depth on both sides and subtract the agreed total clearance to the groove roots. In the selected example, 400 + 8 + 8 − 2 gives 414 mm and 450 + 8 + 8 − 2 gives 464 mm. When centred, 1 mm root clearance on each side leaves 7 mm nominal capture. Production dimensions also include panel/carcass tolerances, movement, insertion and any extra support.

Is support span the same as the overall back or drawer size?

Support span is measured between the actual supporting edges. A selected 600 mm carcass with two 18 mm side rails and one centred 18 mm intermediate rail gives two clear bays of (600 − 18 − 18 − 18) / 2 = 273 mm. The complete furniture design and assessment establish the suitable support, connection, use and load; this calculation describes geometry.

How are opening positions carried from the face to the reverse?

Name F01, F02, the physical D0 corner and the top edge. In the selected 598 mm wide back, a hole centre at X40/Y60 in F01 appears at X558/Y60 from the left edge in the F02 view. D0 remains the same physical corner and appears on the right in that reverse view. Dimension each face-specific operation from its named view and datum.

What does the quotation include for a hardboard furniture set?

We itemize the actual Hardboard sheet or cut parts, product/finished thickness, dimensions, faces, openings, supplied finish, part IDs and quantities. The order also names any included support, fittings or accessories and the furniture operations completed in your workshop. A first fitted sample, current drawing, flat-supported pack and BOM keep the repeat set aligned.
